Ok heres the situation, we have an obd2 car that were swapping a 94 (obd1) b18c1 into. We are keeping the car obd1 but using the original car harness (obd2). Were using an obd1 (chipped p72) ecu with a jumper harness. We swapped the plugs on the obd1 dizzy for an obd2 plug (so we could use the obd1 dizzy with the obd2 car harness) Vtec is not wired up yet but all other preliminary connections are. We fired up the car..it started...we had to idle it manually because we hadnt installed the gsr throttle cable or tps yet. When we tried to start it up again it wouldnt fire up...the dizzy was giving no more spark. So we changed the ignitor and coil (from the obd2 nonvtec distributor we had lieing around) and it still wont give any spark. My question is what could be the problem? Why would the dizzy all of a sudden just stop giving spark and wont give spark after we used a different coil and ignitor? Any help is appreciated

btw i did search but the answers were things i already covered

yea i am haveing similiar problem i have 96 ek with a b20 and it runs when i have the stock obd2 ecu in and i ordered a obd1 conversion harness from skunk2 and we got a chipped p06 and stock obd1 ls ecu and another stock obd1 po6 and when ever we put the jumper on and put a obd1 ecu in he car will not crank it has no spark we even put it on another car and it would not crank up on his car either then put his stuff back on and it cranked up so basically it will not crank when i jump it back to obd1 the only problem that i can come up with is that something is wrong with the jumper i do not know what would be wrong and i do not think all of the ecus are bad i know they are not
